The cross beams are key components of every multihull. Proasis’s beams are made from plywood and timber in a hollow construction. The outside is reinforced with glassfiber. Each beam is 4.5 m long and weights about 25 kg.
Closed beam on the left, open cross section on the right.It doesn’t matter how many clamps you have . . . you will run low! We clamped 40 on each beam and could have used 60 ore more.
